Total Customer Satisfaction – PCB

Piezotronics guarantees Total Customer

Satisfaction. If, at any time, for any

reason, you are not completely satisfied

with any PCB product, PCB will repair,

replace, or exchange it at no charge. You

may also choose to have your purchase

price refunded in lieu of the repair,

replacement, or exchange of the product.

Service – Due to the sophisticated nature

of the sensors and associated

instrumentation provided by PCB

Piezotronics, user servicing or repair is

not recommended and, if attempted, may

void the factory warranty. Routine

maintenance, such as the cleaning of

electrical connectors, housings, and

mounting surfaces with solutions and

techniques that will not harm the

physical material of construction, is

acceptable. Caution should be observed

to insure that liquids are not permitted to

migrate into devices that are not

hermetically sealed. Such devices should

only be wiped with a dampened cloth

and never submerged or have liquids

poured upon them.

Repair – In the event that equipment

becomes damaged or ceases to operate,

arrangements should be made to return

the equipment to PCB Piezotronics for

repair. User servicing or repair is not

recommended and, if attempted, may

void the factory warranty.

Calibration – Routine calibration of

sensors and associated instrumentation is

recommended as this helps build

confidence in measurement accuracy and

acquired data. Equipment calibration

cycles are typically established by the

users own quality regimen. When in

doubt about a calibration cycle, a good

“rule of thumb” is to recalibrate on an

annual basis. It is also good practice to

recalibrate after exposure to any severe

temperature extreme, shock, load, or

other environmental influence, or prior

to any critical test.

PCB Piezotronics maintains an ISO-

9001 certified metrology laboratory and

offers calibration services, which are

accredited by A2LA to ISO/IEC 17025,

with full traceablility to N.I.S.T. In

addition to the normally supplied

calibration, special testing is also

available, such as: sensitivity at elevated

or cryogenic temperatures, phase

response, extended high or low

frequency response, extended range, leak

testing, hydrostatic pressure testing, and

others. For information on standard

recalibration services or special testing,

contact your local PCB Piezotronics

distributor, sales representative, or

factory customer service representative.

Returning Equipment – Following

these procedures will insure that your

returned materials are handled in the

most expedient manner. Before returning

any equipment to PCB Piezotronics,

contact your local distributor, sales

representative, or factory customer

service representative to obtain a Return

Warranty, Service, Repair, and

Return Policies and Instructions

Materials Authorization (RMA)

Number. This RMA number should be

clearly marked on the outside of all

package(s) and on the packing list(s)

accompanying the shipment. A detailed

account of the nature of the problem(s)

being experienced with the equipment

should also be included inside the

package(s) containing any returned

materials.

A Purchase Order, included with the

returned materials, will expedite the

turn-around of serviced equipment. It is

recommended to include authorization

on the Purchase Order for PCB to

proceed with any repairs, as long as they

do not exceed 50% of the replacement

cost of the returned item(s). PCB will

provide a price quotation or replacement

recommendation for any item whose

repair costs would exceed 50% of

replacement cost, or any item that is not

economically feasible to repair. For

routine calibration services, the Purchase

Order should include authorization to

proceed and return at current pricing,

which can be obtained from a factory

customer service representative.

Warranty – All equipment and repair

services provided by PCB Piezotronics,

Inc. are covered by a limited warranty

against defective material and

workmanship for a period of one year

from date of original purchase. Contact

PCB for a complete statement of our

warranty. Expendable items, such as

batteries and mounting hardware, are not

covered by warranty. Mechanical

damage to equipment due to improper

use is not covered by warranty.

Electronic circuitry failure caused by the

introduction of unregulated or improper

excitation power or electrostatic

discharge is not covered by warranty.

Contact Information – International

customers should direct all inquiries to

their local distributor or sales office. A

complete list of distributors and offices

can be found at www.pcb.com.

Customers within the United States may

contact their local sales representative or

a factory customer service

representative. A complete list of sales

representatives can be found at
